“An icebreaker crew has scored one of exploration’s hardiest achievements: sailing to the North Pole. Cutter Healy arrived at latitude 90 degrees north on Saturday, becoming the first U.S. surface ship to make it to the top of the Earth unaccompanied. It is one of only four trips to the pole and the first since 2005, the release said.”
